This exploits the comment lines in the text/uri-list specification:
https://tools.ietf.org/rfc/rfc2483.txt (page 11), which might be a bit
hackish, but the specification suggests doing the same for other uses,
so it should be fine.
This is just the syscalls and error handling that was done for each
file in delete_paths.
This will be used to prevent the unneeded construction of vectors
when performing cut operations
Now that fonts know their own weight, we no longer need highlighters to
tell us which font to use. Instead, they can just say "this should be
bold" and we'll find the right font ourselves.
The compose() function is supposed to be fast since it can execute
60 times per second. Let's not do obviously avoidable things like
configuration value lookups in there. :^)
This is mostly based on TextDocument's similar methods, these will
help implement searching within the terminal application.
The support for unicode code points is shaky at best, and should
probably be improved further.
This was mentioned in #4574, and the more I think about it the more it
feels just right - let's move it there! :^)
Having to link LaunchServer against LibGUI explicitly should've been
telling enough...
It's not an error to create a Userspace<T> that points to kernel memory
as the point of Userspace<T> is not to validate the address, but rather
to choose safe overloads that do validation before any data transfer
takes place.
Fixes#4581.
The partitioning code was very outdated, and required a full refactor.
The new subsystem removes duplicated code and uses more AK containers.
The most important change is that all implementations of the
PartitionTable class conform to one interface, which made it possible
to remove unnecessary code in the EBRPartitionTable class.
Finding partitions is now done in the StorageManagement singleton,
instead of doing so in init.cpp.
Also, now we don't try to find partitions on demand - the kernel will
try to detect if a StorageDevice is partitioned, and if so, will check
what is the partition table, which could be MBR, GUID or EBR.
Then, it will create DiskPartitionMetadata object for each partition
that is available in the partition table. This object will be used
by the partition enumeration code to create a DiskPartition with the
correct minor number.
The DevFS along with DevPtsFS give a complete solution for populating
device nodes in /dev. The main purpose of DevFS is to eliminate the
need of device nodes generation when building the system.
Later on, DevFS will assist with exposing disk partition nodes.
BlockBasedFileSystem::read_block method should get a reference of
a UserOrKernelBuffer.
If we need to force caching a block, we will call other method to do so.
clang trunk with -std=c++20 doesn't seem to properly look for an
aggregate initializer here when the type being constructed is a simple
aggregate (e.g. `struct Thing { int a; int b; };`). This template fails
to compile in a usage added 12/16/2020 in `AK/Trie.h`.
Both forms of initialization are supposed to call the
aggregate-initializers but direct-list-initialization delegating to
aggregate initializers is a new addition in c++20 that might not be
implemented yet.
This changes the signatures for FILE::seek and FILE::tell, to use
`off_t` as they use lseek internally. `fpos_t` is also redefined to use
`off_t`.
Dr. POSIX says that fpos_t is:
> A non-array type containing all information needed to specify uniquely
> every position within a file.
In practice, most *NIX typedef it to `off_t`, or a struct containing an
`off_t` and some internal state.
These two lines caused this local .gitignore to supersede all inputs
in any files specified by a user's `core.excludesFile` configuration
since the first match was going to be `!*.*` for any file with a
decimal or any directory. `git check-ignore -v somefile` can be used to
test this.
